Abstract:Objective:To Investigate the effect of Lyke Granule on simian immunodeficiency Virus(SIV) infection model. SAIDS model were used. Using monoclonal antibody label on CD+4 and CD+8 cells in PBMC with direct immunofluorescence,the percentage was analyzed by flow cytometry and analyzed CD+4/CD+8 ratio. T and B cells proliferation induced by mitogens was defected before treatment and after treatment with Lyke Granule. Results indicate that Lyke Granule enhanced the proliferation of T and B cells induced by motogen,CD+4 T cells were increased in PBMC and CD+4/CD+8 were changed.
